f(3)=(3*3+1)/(3+4i)=10(3-4i)/25=6/5+4i/25
was it f(2+i) or f(2+1) = f(3)?
Sorry! it's f(2+i)!

factorial thats scary
i know thats an exclamation mark
\[f(2+i)=\frac{3(2+i)+1}{2+i+4i}\] what exactly do you want? you seem to be in upper level class so what should i write this as or i mean what is the goal

next door? Louisiana? i think thats spelled right
no arkansas
LOL i added wrong. 14+15 is 29, not 39
see we arent all hicks
you are on the right path alexis, you just need to get the complex number out of the denominator of that fraction.
thats true, we all arent hick lolol
I was never think do mutliply with (2+5i). Thanks a lot guys! :D
\[\frac{7+3i}{2+5i}*\frac{2-5i}{2-5i}=\frac{14-35i+6i-15i^2}{4-5i^2}\]
lol
go eat your breakfast
alright.....breakfast, i'll see you guys later lol
I hope you will be here to answer and at my next questions :D lol

yes i see opossums around here
i thought you were on the west coast. shows you what i know
you doing complex variables problems?
Alexis please review the multiplication of the denominator: (2+5i)(2-5i). It is not:\[4-5i ^{2}\]
because its 4-25i^2 lol
